discrete_gradient

Constructs a discretized gradient along time/height. The gradient value between
<code>bounds[i]</code> and <code>bounds[i+1]</code> (not including) is <code>vals[i]</code>, values above/below the largest/smallest value of <code>bounds</code> are assigned <code>outval</code>.
Helper function for usage with <code>discrete_niche</code>

The fossil record is a joint expression of ecological, taphonomic,
evolutionary, and stratigraphic processes (Holland and Patzkowsky, 2012, ISBN:978-0226649382).
This package allowing to simulate biological processes in the time domain
(e.g., trait evolution, fossil abundance), and examine how their expression
in the rock record (stratigraphic domain) is influenced based on
age-depth models, ecological niche models, and taphonomic effects.
Functions simulating common processes used in modeling trait evolution or
event type data such as first/last occurrences are provided and can be used
standalone or as part of a pipeline. The package comes with example
data sets and tutorials in several vignettes, which can be used as a
template to set up one's own simulation.
